Paper Abstract

A direct experimental observation of chaotic synchronous scenarios, namely chaotic optical modulation, is demonstrated in a unidirectional chaotic-coupling semiconductor laser system. In this fully optical system, the channel signal is different from the output field of the transmitter laser by an additional monochromatic optical field. Different from the chaos synchronization explainable by theory of chaos synchronization, the output field of the receiver laser is not synchronized to that of the transmitter laser. Instead, it is synchronized to the channel signal. However, the optical frequency of the receiver is not locked to that of the transmitter. It is observed that not only is the intensity of the receiver output is synchronized to that of the channel signal, but also the chaotic slowly-varying phase of the receiver. The synchronization of the slowly-varying phase is verified by optical interference between the output of the receiver and the channel signal, and the interference result is recorded through a photodetector.
